TrixiParticles.jl: Particle-based multiphysics simulations in Julia

Abstract

TrixiParticles.jl is a Julia-based open-source package for particle-based multiphysics simulations and part of the Trixi Framework (Schlottke-Lakemper et al., 2021). It handles complex geometries and specialized applications, such as computational fluid dynamics (CFD) and structural dynamics, by providing a versatile platform for particle-based methods. TrixiParti-cles.jl allows for the straightforward addition of new particle systems and their interactions, facilitating the setup of coupled multiphysics simulations such as fluid-structure interaction (FSI). Furthermore, simulations are set up directly with Julia code, simplifying the integration of custom functionalities and promoting rapid prototyping. Here, we give a brief overview of the software package TrixiParticles.jl, starting with the scientific background before going on to describe the functionality and benefit in more detail. Finally, exemplary results and implemented features are briefly presented.
